The AN/SQQ-23 is basically the AN/SQS-23 system retrofitted for computer coordinated capability. It operates in single alert, dual alert, dual non-alert modes, with search capabilities that include: B-scan, TDC, correlogram track display, doppler display and passive: time-bearing recording (TBR). It is like two stacks of AN/SQS-23 for double detection using different frequencies. The AN/SQS-23 was a long range, azimuth-scanning type of search and attack sonar used for search, search-analyze, attack-RDT, attack-SDT and hand-key applications. Installed in DDG-2 and DDG-16 class ships, it used the Ship center display (SCD) for search operations and target center display (TCD) for attack.
